Engine:
First, global initialization
The JS engine needs to complete the following three initialization tasks as it enters a piece of executable code:
First, create a global object that has only one global object, its properties accessible anywhere, and its presence along with the entire lifecycle of the application. When a global object is created, it uses the common JS objects such as math,string,date,document as its properties. Since this global object cannot be accessed directly by name,

global Execution environment (Execution Context) EC, and press the global execution environment EC into the execution environment stack. The execution environment stack is used to ensure that the program can be executed in the correct order. In javascript, each function has its own execution environment. When a function is executed, the execution environment of the function is pushed to the top of the exec
In an abstract class, you can include one or more abstract methods, but in an interface (interface), all methods must be abstract and cannot have a method body, which is more "abstract" than an abstract class.Interfaces are declared by using the interface keyword, which can be seen as a special abstract class that specifies what a class must do, not how it is to be done.In reality there are also many examples of interfaces, such as the serial computer hard disk, Serial ATA Commission designated
device is using a terminator, the SCSI card will not be able to find a later SCSI device. SCSI also does not work if the last device does not use a terminator. The Terminator is made up of resistors, located at the end of the SCSI bus, to reduce the interaction between the signals and maintain a constant voltage on the SCSI chain.Most SCSI devices are built-in terminators and use a jumper to control on/off. SCSI devices are now highly intelligent and can automatically control Terminator On/off,

Due to SSD read/write latency and iops (I/O perSecond) These two aspects have about three orders of magnitude advantage over traditional mechanical hard drives, which has led some people to doubt the prospect of mechanical hard drives, I think SSD will be the first choice in the cloud computing era and will completely re
For developers who do not understand network programming, Writing a good service-side communication program is a hassle. However, with the EC this free component you can easily build a network service program that runs on a Linux or win-only deployment. This convenience is fully benefited from the continuous development of mono over the years. Here's how this component through the EC passes in just 10 minut

and sweep receiver to collect data. The sweep receiver should be used with GPS so that the signal can be unlocked on the correct pilot frequency. As the sweep receiver data does not depend on the activation of the network or the processing of the call (including the neighborhood list, switching, activation settings size, search window, etc.), it can reveal problems in the RF (for example, PN is not in the Search window, the same area has more than six pilot signals, etc.).

, because it contains a dependency on the EC (Embedded Controller), make it impossible to invoke in the _ini method. In this case, the entire _off method or part of its code needs to be moved to the _reg method for deferred execution (when the _reg method receives the parameters arg0==3 and arg1==1, it is executed after the _ini method) (see ACPI specification). In some cases, it is too late to call _off in the _reg method, which results in either a b
